COI maximum likelihood phylogeny of Antarctic sponges (in bold face) belonging Order Poecilosclerida (chelae-bearing).

open access: yes, 2015
For visualization, subtrees containing Antarctic sponges were pruned from the complete phylogenetic tree that included all sequences analyzed (i.e. GenBank + sequences from this study). Bootstrap support is given near each branch of the tree.

Mapping water content in drying Antarctic moss communities using UAS‐borne SWIR imaging spectroscopy

open access: yesRemote Sensing in Ecology and Conservation
Antarctic moss beds are sensitive to climatic conditions, and both their survival and community composition are particularly influenced by the availability of liquid water over summer.

The effect of non-linear internal waves on the growth of Antarctic sponges

open access: yes, 2016
Non-linear internal waves (NLIW or solitons) are generated where strong tidal flows interact with bottom topography in stratified waters. Here we report on solitons of exceptional amplitude (>200 m) in the Antarctic peninsula region enhancing diapycnal ...

Chemical and biological screening of deep-water sponges from Antarctic regions

open access: yes, 2016
The majority of marine natural products (MNPs) originate from tropical and temperate shallow water invertebrates, such as sponges [1]. Recent studies indicate the presence of great genetic diversity in deep-waters that may be linked to unprecedented ...

Cold Biosilicification in Metazoan: Psychrophilic Glass Sponges

open access: yes, 2016
Numerous species of sponges (Porifera) habituate cold waters, including Antarctic seas. Silica-based skeletal structures, including spicules and skeletal frameworks, of representatives from both Demospongiae and Hexactinellida taxons arise due to ...
